Untreated vs. treated tree
The Emerald Ash Borer (EAB) is a threat to all Ash trees. Nevertheless, while this invasive species related to the beetle is highly invasive and aggressive, it can be spotted, prevented and even treated in many cases.
Particularly if you catch an EAB infestation at a reasonably early stage and work proactively, there may be a chance of saving the Ash trees on your property.
As mighty as an Ash tree may appear, it can be brought down surprisingly easily by these tiny but incredibly dangerous little insects.
Just take a look at the photo to the right, which features one tree that was treated for EAB infestation and one that wasn’t, to get a sense of the level of destruction these pests are capable of causing.

Here are some pictures of Ash trees I took in 2012. These trees were found to be infested by Emerald Ash Borer (EAB). The location was the Hampton Greens Condominiums in Warrington, Bucks County. This was the first documented case of Emerald Ash Borer in our area.
There were thousands of D-shaped exit wounds where the females emerged to either lay more eggs further down the tree, or fly off to other Ash trees and lay eggs in the tops of those trees. It was estimated that these trees had suffered three years of activity by the time these pictures were taken. They were cut down soon after.
